120Make sure you have ethylene-glycol
antifreeze in the radiator.
Do not use alcohol type antifreeze.
NOTICE
Check the condition of the battery and cables. Cold temperatures reduce the capacity of
any battery, so it must be in top shape to provide enough power for winter starting.Chapter 7-3 tells you how to visually in-
spect the battery. Your Toyota dealer and
most service stations will be pleased tocheck the level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See Chapter 7-2 for recommended vis-
cosity.
Leaving a heavy summer oil in your
vehicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Toyota dealerÐ
he will be pleased to help. Keep the door locks from freezing. Squirt lock de-icer or glycerine into the
locks to keep them from freezing. To open
a frozen lock, try heating the key before in-serting it. Use a washer fluid containing an anti-
freeze solution.
This product is available at your Toyota
dealer and most auto parts stores. Follow
the manufacturer's directions for how
much to mix with water.NOTICE
Do not use engine antifreeze or any other substitute as washer fluid be-
cause it may damage your vehicle's
paint.
Do not use your parking brake when there is a possibility it could freeze. When parking, put the transmission into
Pº (automatic) or into first or reverse
(manual) and block the rear wheels. Do
not use the parking brake, or snow or wa-
ter accumulated in and around the parkingbrake mechanism may freeze, making it
hard to release. Keep ice and snow from accumulating
under the fenders.
Ice and snow built up under your fenders
can make steering difficult. During bad winter driving, stop and check under the
fenders occasionally. Depending on where you are driving,
we recommend you carry some emer- gency equipment.
Some of
the things you might put in the ve-
hicle are tire chains, window scraper, bag of sand or salt, flares, small shovel, jump- er cables, etc.
Winter driving tips

121
Toyota does not recommend towing a
trailer with your Supra. It is not designed for trailer towing.Getting
more kilometers/mileage from a li-
ter/gallon of fuel is easyÐjust take it easy.
It will help make your vehicle last longer,
too. Here are some specific tips on how to
save money on both fuel and repairs: Keep your tires inflated at the cor- rect pressure. Underinflation causes
tire wear and wastes fuel. See Chapter
7-2 for instructions.
Do not carry unneeded weight in
your vehicle. Excess weight puts a
heavier load on the engine, causing greater fuel consumption.
Avoid lengthy warm-up idling.
Once the engine is running smoothly,
begin drivingÐbut gently. Remember,
however, that on cold winter days this
may take a little longer.
Accelerate slowly and smoothly.
Avoid jackrabbit starts. Get into high
gear as quickly as possible.
Avoid long engine idling. If you have
a long wait and you are not in traffic, it
is better to turn off the engine and start
again later.
Avoid engine lug or overrevving.
Use a gear position suitable for the
road on which you are travelling.
Avoid continuous speeding up and
slowing down. Stop-and-go driving
wastes fuel.
Avoid unnecessary stopping andbraking. Maintain a steady pace. Try
to time the traffic signals so you only
need to stop as little as possible or take
advantage of through streets to avoid
traffic lights. Keep a proper distance
from other vehicles to avoid sudden braking. This will also reduce wear on your brakes.
Avoid heavy traffic or traffic jams
whenever possible.
Do not rest your foot on the clutch
or brake pedal. This causes needless
wear, overheating and poor fuel econ-
omy.
Maintain a moderate speed on highways. The faster you drive, the
greater the fuel consumption. By re-
ducing your speed, you will cut down
on fuel consumption.
Keep the front wheels in proper alignment. Avoid hitting the curb and
slow down on rough roads. Improper
alignment not only causes faster tire
wear but also puts an extra load on the
engine, which, in turn, wastes fuel.
Keep the bottom of your vehicle
free from mud, etc. This not only
lessens weight but also helps prevent corrosion.

your vehicle last longer, too

126Do not connect the cable to or near any
part that moves when the engine is cranked.
NOTICE
When making the connections, do not lean over the battery or
accidentally let the jumper cables or clamps touch anything exceptthe correct battery terminals or the ground.
5. Start your engine in the normal way.
After starting, run it at about 2000 rpm for several minutes with the accelerator ped-
al lightly depressed.
6. Carefully disconnect the cables in the
exact reverse order: the negative cable
and then the positive cable.
7. Carefully dispose of the battery cover
clothsÐthey may now contain sulfuricacid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is
not apparent (for example, lights left on), you should have it checked. If your engine stalls while driving
0
1. Reduce your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see If your ve-
hicle will not startº.If the engine is not running, the
power assist for the brakes and
steering will not work so steering
and braking will be much harder
than usual. CAUTION
! If your engine coolant temperature
gauge indicates overheating, if you
experience a loss of power, or if you
hear a
loud knocking or pinging noise,
the engine has probably overheated.
You should follow this procedure 0
1. Pull safely off the road, stop the vehicle
and turn on your emergency flashers. Put
the transmission in Pº (automatic) or neu-
tral ( manual) and apply the parking brake.
Turn off the air conditioning if it is beingused.
2. If coolant or steam is boiling out of the
radiator or reservoir, stop the engine. Wait
until the steam subsides before opening
the hood. If there is no coolant boiling over or steam, leave the engine running.
To help avoid personal injury, keep
the hood closed until there is no steam. Escaping steam or coolant
is a sign of very high pressure. CAUTION
!
3. Visually check to see if the engine drive
belt (fan belt) is broken or loose. Look for
obvious coolant leaks from the radiator,
hoses, and under the vehicle. However, note that water draining from the air condi-
tioning is normal if it has been used.
If your vehicle overheats
If your engine stalls while driving

127
When the engine is running, keep
hands and clothing away from the
moving fan and engine drive belts.CAUTION
!
4. If the engine drive belt is broken or the
coolant is leaking, stop the engine immedi-
ately. Call a Toyota dealer for assistance.
5. If the engine drive belt is O.K. and there are no obvious leaks, you may help the en-
gine cool down more quickly by running it
at about 1500 rpm for a few minutes with the accelerator pedal lightly depressed.
6. Check the coolant reservoir. If it is dry,
add coolant to the reservoir while the en- gine is running. Fill it about half full.
Do not attempt to remove the radia-
tor cap when the engine and radia-
tor are hot. Serious injury could re-
sult from scalding hot fluid and
steam blown out under pressure. CAUTION
!
7. After the engine coolant temperature
has cooled to normal, again check the
coolant level in the reservoir. If necessary,
bring it up to half full again. Serious cool-ant loss indicates a leak in the system.
You should have it checked as soon as
possible at your Toyota dealer. 1. Reduce
your speed gradually, keeping
a straight line. Move cautiously off the
road to a safe place well away from the
traffic. Avoid stopping on the center divid-
er of a highway. Park on a level spot with firm ground.
2. Stop the engine and turn on your emer-
gency flashers.
3. Firmly set the parking brake and put the transmission in Pº (automatic) or re- verse (manual).
4. Have everyone get out of the vehicle
on the side away from traffic.
5. Read the following instructions thor-
oughly.When jacking, be sure to observe
the following to reduce the possi-
bility of personal injury: Follow jacking instructions.
Use a jack only for lifting your ve-
hicle during wheel changing.
Never get beneath the vehicle
when supported by a jack.
Do not start or run the engine
while your vehicle is supported
by a jack. CAUTION
!
NOTICE
Do not continue driving with a deflated tire. Driving even a short
distance can damage a tire beyond repair.
If you have a flat tireÐ
